Background: The present study was conducted for evaluating fracture resistance of endodontically treated teeth restored with different type of post. Materials & methods: 60 freshly extracted maxillary mandibular first molar was included. Following three study groups were made with 20 specimens in each group:Control group: Root-filled teeth without endodontic posts, Group A (ZRP group): Root-filled teeth with prefabricated zirconia post, and Group C (GFP group): Root-filled teeth with prefabricated glass fiber post. Removal of the canal filling material was done followed by post space preparation and coating with freshly mixed self-adhesive resin cement. Each post was seated with finger pressure for 10 s. afterwards; all the specimens were loaded in aa universal testing machine (until fracture occurrence (in Newton). Results: Mean fracture load resistance among specimens of group 1, group 2 and control group was 723.1 N, 796.2 N and 513.8 N respectively. While comparing the results, significant results were obtained. Conclusion: Prefabricated glass fiber post had maximum fracture resistance.
